Eucliwood is a necromancer who brought Ayumu back to life to be her guard and has been living with him since. Her magic is so powerful that she has to wear heavy armor and suppress her emotions in order to control it. Her words also carry strong magic, and she is able to kill someone just by saying "Die", so she avoids talking and instead communicates through written notes, mostly pertaining to her appetite.She experiences severe pain whenever her magic is activated, and she claims that even if she were to die her magic would continue uncontrolled.
